1 Claim.

This invention relates to new and useful improvements in window and door constructions and has particular relation to weather'stripping for such constructions.

The objects and advantages of the invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claim.

Fig. 1 is a front elevational'view of a easement window having the weatherstripping of the invention applied thereto;

Fig. 2 is an enlarged sectional view taken as along the line 2-2 of Fig. 1;

Fig. 3 is a front elevational View of a double hung window having my weather stripping applied thereto;

Fig. 4 is an enlarged sectional view taken as along the line 4-4 of Fig. 3; and

Fig. 5 is a perspective view of an end portion of the weather strip of the invention.

While in the accompanying drawing and following description my improved weather stripping is shown and described as specically applied to easement and double hung windows i1; is to be understood that the invention is not limited to such applications since the weather stripping of the invention may obviously be applied to doors and the like. Therefore, wherever in the following specification and claim the structure specied is applicable to door constructions it is to be understood as covering the same, the word winidow ybeing intended to comprehend other closures such as doors.

Referring in detail to the drawing and at iirst more particularly to Figs. l and 2 at lil is generally indicated the frame of a easement window including vertical jambs II and I2 on which are mounted sashes I3 and I4 respectively. As here shown hinges I5 serve to mount the sashes for movements between open and closed positions. The sashes are of similar construction and sash I3 includes a hinged rail I6 and a free rail Il while sash I4 includes a hinged rail I8 and a free rail I9.

A weather stripped joint is provided between the free sash rails I'I and I9 and the details of this joint will be best understood by reference to Figs. 2 and 5. It will be noted in Fig. 2 that the edges of the rails I'I and I9 which are located in opposand 2|. These vstrips areeof identical construction and Yeach includes an elongated plate-like portion v22 having one longitudinal edge curved in-to one side of the-plate to provide a channel 23 and having its other longitudinal` edge portion Y curved in the opposite direction providing a channel 24. Intermediate its longitudinal edges the plate is providedwith a bead 25. Actually channel 24-is of. a size to receive the channel 23ibeing curved onr a somewhat largerfradius.

Throughitschannel portion 25 each plate is provided with openings 26 for the passage of screws or other securing means 2l and such channel portions 25 of the plates are disposed in grooves, provided for their reception, in the beveled edge portions of the rails I'I and I9. The strips 20 and 2| are secured to the rails with one strip in reversed position relative to the other. That is, larger radiused channel 24 of the plate 2I is at the outer side of the rail I9 while the larger radiused channel 24 of the strip 20 is at the inner side of rail I1.

Thus -when the Window sashes I3 and I4 are closed the smaller radiused channel 23 of each strip enters or is received in the larger rediused channel 24 of the other strip. The smaller radiused channels have snug ts in the larger radiused channels so that when these channels are in engagement or nested in one another as in Fig. 2 air may not .blow in between the strips 2l] and 2|. In addition the channels 25 of the strips be ing snugly embedded in the beveled faces of the rails I1 and I9 air may not blow into the room by passing between the strips and the rails on which they are mounted.

Due to the nesting of the channels of smaller radii in the channels of larger radii when the sashes are closed the weather strips are interlocked with one another. However, the sashes may be readily opened since it will be apparent that due to the beveled construction the sash I3 may be readily swung inwardly to open position after which the sash I4 may be similarly swung to open position. If it is desired that the sashes swing outwardly to open `positions it is only necessary to make the installation by reversing the mountings from that here shown.

From the above it will be clear that with the construction disclosed closing of the sashes provides a weather tight joint at the free or meeting rail joints. Attention is also directed to the fact that where but a single easement sash is used one of the strips 20, 2l will be mounted on the free rail of said sash while the other strip will be mounted on the frame jamb adjacent where said rail is located when the sash is closed. As above suggested the weather stripping construction herein disclosed is not restricted to use with easement Windows but may be used on double hung windows and in connection with doors and the like.

Referring now to Figs. 3 and 4 the weather stripping of the invention is there shown as incorporated in a double hung window. In suchY figures the window frame is generally designated 36 and mounted in the same for sliding movement are upper and lower sashes 3| and 32 respectively. Such sashes include meeting rails comprising the lower rail 33 of the upper sash and the upper rail 34 of the lower sash.

On the opposing faces of such rails are mounted weather strips 20a and Zla of the construction above described. These strips are mounted in the manner above described, their beads 25 being embedded inv the rails 33 and VIdrespectively. The strips being secured in place by screws 35 or the like air may not pass between the strips and the rails to which the strips are secured.l

Additionally when the sashes are closed and the smaller radiused channels 23 are locked snugly in the larger radiused channels 24 air may not pass between the' two strips so interlocked. With the double hung'window it is not necessary to bevel the opposing faces of the meeting rails 33 and 34 since any relative movement of the sashes takes place vertically so that the strips 20a and 2Ia readily clear one another.

It will now be clear that the weather stripping of the invention is not restricted in its application to hinged closures but is readily applicable to sliding closures such as double hung windows and the like.

The present application is a division of my application Serial Number 359,112, filed September 30, 1940.

Having thus set forth the nature of my invention, what I claim is:

In a window construction, relatively movable sashes having meeting rails vincluding opposing faces located closely adjacent one another when the sashes are both in closed position, a metal weather strip on each of said faces for sealing the joint between them when the sashes are closed, each of said weather strips including an elongated metal strip having an intermediate longitudinally extending hollow bead of substantially the length of its strip and snugly embedded in a groove in the opposing face of its rail to establish a seal between the strip and its rail, headed means passing through the bead portion of said strips and into the respective rails and f securing the strips to their rails with the heads 30 than those at the other edge thereof, said channel of less size on each strip of a size to fit in the channel of larger size of the other strip when said sashes are closed,'and said strips secured on their rails with the free edge portions of the 35 strips at the channels of less size against a second face of the rail to which its strip is secured.
